ATTORNEY Patented Mar. 6, 1934 UETED STATES TOBAC CO PIPE Paul Ehorn, Sacramento, Calif.

Application October 31,

5 Claims.

This invention relates to smokers pipes, my principal object being to provide a pipe of this character so constructed that the juices exuding from the burning tobacco as well as any saliva which may flow along the stem toward the bowl will be dried up by the heat generated by the burning tobacco. The pipe will therefore remain in a desirable dry condition at all times. The pipe is also constructed so that a better cooling action is imparted to the smoke after it leaves the bowl than is the case with the ordinary pipe.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a longitudinal elevation of my improved pipe mainly in section showing the drying device mounted therein.

Fig. 2 is a sectional view of the bowl detached from the stem showing the drying device in section.

Fig. 3 is a perspective view oi the drier detached.

Referring now more particularly to the characters of reference on the drawing, the numeral 1 denotes the mouthpiece and stem member of the pipe which may be of any desired shape and material and which is removably fitted onto the shank 2 of the bowl 3 in the conventional manner. The stem has a smoke passage 4 extending therethrough which communicates with a blind passage 5 in the shank. The passage 5 and the adjacent portion of the passage 4 are sufficiently large to form a smoke cooling chamber, the passage 4 at its outer end being constricted to the usual narrow slit-like form.

The bowl 3 depends from the level of the top of the shank 2 and is formed with a bottom cuplike cap 6 which removably screws onto the bowl as plainly shown. The diameter of the cap bore 7 is larger than that of the bowl itself so that the lower end of the bowl proper, at its junction with the cap, will overhang the cap bore. A locating space is thus formed in the cap for the reception of a cylindrical metal member 8 removably fitting into the cup bore and held against undesired removal by the overhanging bowl.

This member is hollow and is in the form of an inverted cup, a separate metal disc 9 forming a bottom for the cup resting in the bottom of the cap bore under the member 8. Since the memher 8 is preferably thin on top it is formed with 1932, Serial No. 640,359

2. central depressed boss 10 which bears against the disc 9 and prevents undesired sagging or buckling of said top. A circular chamber 11 is thus formed in the member 8 about said boss, the top of said member having a plurality of small holes 12 drilled about the same to provide communication between the bowl and the chamber.

Projecting upwardly from the member 8 toward one side and at a diverging angle to the axis of the bowl is a tube 13, of the same metal as that of which the member 8 is made. This tube projects through a hole 14 drilled in the adjacent side of the bowl at a corresponding angle to communicate with the bottom of the passage 5 at its inner blind end. Intermediate its ends and on the side facing the bowl the tube is formed with a boss 15 whose outer face lies flush with and follows the contour of the bore of the bowl as shown; a socket being cut in the bowl in connection with the hole 14 to receive said boss.

By means of this construction it will be seen that smoke from the burning tobacco is drawn through the holes 12 into the chamber 11 and thence up the tube 14 into the passage 5, whose relatively great area cools the smoke before it is drawn into the mouth. As long as the bowl is relatively full of unburnt tobacco very little trouble is encountered from tobacco juices etc. since the unburnt tobacco at the bottom of the bowl will absorb such liquid matter.

As the amount of unburnt tobacco is decreased with the continued smoking of the pipe the quantity of liquid gravitated toward the bottom of the bowl is increased since the tobacco is unable to absorb the same. By that time however the boss 15, and subsequently the lower portion of the tube 13, which projects into the bowl, are directly exposed to the burning tobacco and become heated. Since the metal of which the member 8 and the tube 13 are made is of a character having great heat conductivity, said tube and the member 8 heat up very quickly so that liquid cooling in the chamber 11 is almost immediately dried by the heat and the smoke passing through said chamber and tube 13 will be drawn into the passage 5 in a dry condition. As the tobacco burns still lower in the bowl and imparts its heat directly to the top of the member 8 the drying action is of course increased.

Whenever it is necessary to clean out the drier it is only necessary to first unscrew the bottom cap 6 which permits withdrawal or" the drying member and tube from below for ready cleaning and unclogging of the holes 12 should this be required.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

l. A tobacco pipe comprising a bowl, a shank projecting from the bowl adjacent the top and having a blind bore leading from its outer end, a passaged stein connected to the shank to communicate with said bore, and a heat conducting smoke passage member leading from the bottom or" the bowl to the shank bore and exposed in part to the interior of the bowl.

2. A tobacco pipe comprising a bowl, a shank projecting from the bowl adjacent the top and having a blind bore leading from its outer end, a passaged stem connected to the shank to communicate with said bore, a member separate from the bowl disposed in the bottom of the bowl and forming a chamber separate therefrom, said member having smoke openings through its top surface, and a tube connected to said member to communicate with the chamber and leading to the shank bore.

3. A tobacco pipe comprising a bowl, a shank projecting from the bowl adjacent the top and having a blind bore leading from its outer end, a passaged stem connected to the shank to communicate with said bore, a member separate from the bowl disposed in the bottom of the bowl and forming a chamber separate therefrom, said member having smoke openings through its top surface, and a tube connected to said member and extending upwardly at a diverging angle to the axis of the bowl and through the adjacent side of the same to the bottom of the shank bore.

4. A structure as in claim 3, in which the bottom of the bowl is formed as a removable cap in which said chamber member is removably supported.

5. A structure as in claim 3, in which the tube is formed intermediate its ends with a boss of such size and shape that its vertical face will lie substantially flush with the adjacent side of the interior of the bowl.
